Docker Image won't create due to conda's environment.yml inconsistencies

[Asher Yartsev]

when executing docker-compose up from my Macbook Pro, DockerFile would fail on step 26/35 for non satisfied libs for numpy=1.13.0 dep. (blas,mkl etc.)

so I made some modifications to make it work:
environment.yml

• under channels section I added - https://conda.anaconda.org/conda-forge/ to be the last url.

• under dependencies add - blas on top of others. and removed - matplotlib since for some reason it freeazed the process.

Dockerfile

• change Anaconda2*.sh file to latest Anaconda2*.sh`

• change:
  RUN conda env create -f /root/sac/environment.yml \ && conda env update
  to:
  RUN conda env create -n sac
RUN conda env update
RUN conda export -f /root/sac/environment.yml

I believe this will save someone's time in future and strongly suggest to test and commit those changes @haarnoja
